Walking into the San Francisco Library in Bernal Heights on a Saturday afternoon, I see it’s packed with excited, brightly clad kids and caregivers here for story time. Instead of a librarian, they’re circled around a tall figure. Wearing a black sequined gown, stilettos, and a platinum blonde wig, and seated with a book in her long painted nails, it's Yves St. Croissant, aka Sean Santos, one of San Francisco’s beloved Drag Queens.
